Abstract

A support device includes a bracket secured on a base for rotatably supporting a roller and for engaging with and for supporting a work piece. A stick is secured in the base and has an orifice for slidably engaging with a rod which is extended downward from the bracket for allowing the bracket to be adjusted to a suitable height. The bracket includes a pair of blocks for slidably receiving a pair of poles. The poles each includes an extension extended upward for engaging with the work piece and for preventing the work piece from moving laterally.
